METAL-BENDING- DEVICE.

Specification of Letters Patent.

ratented oef. 2s, 1919.`

Application filed August 12, 1918. Serial No. 249,471.

To all whom t may concern.'

Be it known that I, PERCY SATTERLEE, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Metal-Bendinof Devices, of which the following is a specilcation, referencebeing had therein to the accompanying drawings.

My invention aims to provide novel device or tool for bending angleirons, rods, wires and various kinds of stock, the bending beingexpeditiously and safely performed and in a manner which insures uniformbends when a plurality of pieces of stock are to be similarly shaped. Y

My invention aims to provide a tool that may be advantageously used forbending rey inforcing rods and wires in Concrete construction, forbending the projecting ends of rods or bracket Wires in concreteoonstruction where these rods and wires project from the wall for thepurpose of supporting moldings and ledges, and as a bench tool forbending clips and other articles for building construction. Toaccomplish such bending for the above and other purposes the tool isnecessarily adjustable to' accommodate different kinds of stock andpermit of the stock being bent to desired form.

My invention further aims to accomplish the above results by a simple,durable, portable and inexpensive device that will be hereinafterspecifically described and then claimed.

Reference will now be had to the drawing, wherein there is illustrated apreferred embodiment of my invention, but it is to be understood thatthe structural elements are susceptible to such variations andmodifications as fall within the scope of the appended claims.

In the drawings,

Figure 1 is a perspective view of a metal bending device;

Fig. 2 is a plan of the same, partly broken away, and

Fig. 3 is a cross-sectional view taken on the line III-III of Fig. 2.

In the drawing, the reference numeral 1 denotes an arm having the outerend thereof provided with a flat semi-circular head 2, and adjacenttherstraight edge 3 of said'head Vso that various kinds of is anoverhangin bracket 4' disposed 'in parallelism with t ehead 2 andpreferably formedintegral with said head at its juncture with the arm 1.The bracket 4 has an upstanding lug 5 and said lug is apertured toreceivel a screw or stove bolt 6 for holding a face plate 7 inengagement with said lug, said bolt having slotted shims or washers 8and a nut 9. With such fastening means as the bolt 6 and nut 9, Vit ispossible to place the shims 8 between the lug 5 and the face plate 7,and such adjustments may be made stock. may be bent or shaped bythedevice.

The bracket 4, adjacent the lug 5, has an oblong opening 10 aliningwithy a .similar opening 1l in the head 2 and these openings have wallsinalinement with one side of a depending channel shaped member V12carried by the head 2 and adapted for holding an invertible post 13.The'post 13 conforms in cross sectional area to the openings 10 and l1,said post extending therethrough and confronting the face plate 7 of thelug 5. The post has its ends apertured, as at 14, and one end thereofreduced as at l5, the apertures 14 permitting of either end ofthe postbeing attached to the member 12`by a screw bolt 16 and a nut 17. end ofthe post 13 permits of said post being inverted to increase the Vspacebetween the upper end of the post and the face plate7 ofthe lug 5.

Held between the head 2 and the bracket 4 by the post 13 is anon-rotatable eccentric 18 surrounded by the head 19 of an arm 20 saidarm being free to swing about the eccentric between the bracket 4 andthe head2 of the arm 1.

The head 19 of the arm 20 is provided withran oblong apertured boss 21and mounted in one of the apertures of said boss is a detachable stud 22supporting a revoluble anti-frictional roller 23, and the distancebetween said stud and the post 13 may be decreased by adjusting the studfrom the position shown to the inner end of the boss 21.

The arm 20 is provided with a depending lug 24 adapted to ride againstthe semi-circular wall 25 of the head 2, and this semi- -circular wallor the top of said head may be marked to indicate the position to whichthe arm 20 -has been swung over said head,

consequently it is possible to uniformly bend a plurality of pieces ofstock.

The arms 1 and 2O are apertured, as at 26 so that the arm 1 may besecured to a bench or suitable support or power operating means may beattached to vsaid arms.

For the convenience of describing ythe use of the device I will considerthe arm 1 as stationary and the arm 20 as the operating or bendingelement of the device. The arm 2O has been shown as in extreme position,and assuming that said arm is swung in front of the head 2 in proximityto the arm 1, a piece of stock is placed between the post 13 and theface plate 7 of the lug 5, with the stock end to be bent protrudingoutwardly from the post 13 over the head 2. T he arm :2O is then broughtinto engagement with the end of the stock, and in reference to Fig. 2,swung in a clockwise direction, causing the end of a piece of stock Vtobe bent around the faces of the post 13, the curva.- ture of the benddepending on how far the arm 20 is shifted. With the arm 2O in anextreme position, as shown in Fig. 2, the end of a piece of stock willbe practically bent on itself or in parallelism with the body of thestock.

lith the pivoted end of the arm 20 in eccentric relation to the post 13,the stud 22 approaches the post 13 when the arm 20 is retracted tonormal position, and as said arm is swung during a bending operation,the stud 22 travels away from the post 13 and through the medium of theantifrictional roller 23 gradually bends a piece of stock without anydanger of the same cracking or suddenly snapping. A sharp bend maybevmade by adjusting the stud 22 to a position close to the post 13 andit is through the medium of the shims or filler plates 8 and theinvertible post 13 that p-ieces of stock of different thicknesses may bebent by the device.

1. A metal bending device comprising arms adapted to be manually movedto and from each other, one of said arms having a head and anoiferhanging bracket, an invertible post extending through the head andbracket of said arm, means carried by said bracket adapted for holding apiece of stock thereon, the other arm being eccentrically held by saidpost between the head and bracket of the first-mentioned arm, and a studcarried by the last-mentioned arm and adapted to coperate with said postin bending'a piece of stock placed on said bracket.

2. A metal bending device comprising a stationary arm having ahead and abracket, an invertible post extending through the head and bracket ofsaid arm and having one end thereof held below said head, adjustablemeans carried by said bracket and confronting said post adapted forholding a piece of stock in engagement therewith, said post having oneend thereof smaller than the other so that said post may be inverted toincrease or decrease the space between said post and said adjustablemeans, an eccentric on said post between the `head and bracket of saidstationary arm, a. m0vable arm held by said eccentric to swing over thehead of said stationary arm, and a stud on said movable arm adjustableto and from said post and adapted to coperate therewith in bending apiece of stock held in engagement with said post.

In testimony whereof 1 affix my signature in the presence of twowitnesses.
